How do I perform Implicit Derivative in MathCad?I am trying to use MathCad Prime to solve an implicit derivative but I have no idea how I could do it. It seems to only solve a normal differentiation with only one variable.Example:x^2+y^2=25dy/dx = -y/xHow do I get MathCad to work properly with implicit derivative?Thanks!

I would like to create the web-sheet for calculation S and L between two place on Earth with geo coordinate.Finish please the sheet in attach!

Can a variable's symbolically obtained value be propagated to future uses of that variable?I want my second expression to see c2 as zero.

Hi allI would like to ask you a question about a resolution of equation.According to the attached example, I wonder if MathCad 15 or Premium 3.1 can do and if this is the case if you had an example of market to follow.Kind regards.Denis

I am trying to use MathCad Prime to solve an implicit differentiation but I have no idea how I could do it.It seems to only solve a normal differentiation (functions).Example (circle equation):x^2+y^2=25dy/dx=-x/yHow do I get MathCad Prime to work properly with implicit differentiation?Thanks!

Considering mathcad A very powerful  calculation tool, I can not accept that in calculating the Laplace transform of the square root of t square, + a-squared, I have to resort to the tables. One can not intervene in some way, for example giving the user the possibility to expand the set of transformed?Thanks for the attentionYours sincerely.F. M.

  Hello, Everyone.  Is there a reason for : "All evaluations resulted in either an error or a complex result." ?      Regards.

Hi.   How can I make the graph in Mathcad prime similar to this figure. Do I have a missing formula ?

I'm using MathCAD 15 in Windows 7 environment. I'm trying to create a vector using a range variable or at least that's what I think I'm doing. I thought I could set up a similar command sequence in user defined function as below:But as you can see in my user defined function, MathCAD is not happy with me or range variables don't work the same way in a user defined function as they do in the regular environment.

Hi, I have a problem with using solve block find function multiple inputs, May I know what is the problem? thanks

In the attached Mathcad Prime 3.1 single page worksheet (with pdf print) I am attempting to find the centroid of multiple distributed loads on a beam. The equations work for a single distributed load but I am attempting to make them work for as many distributed loads as the user would like to enter into the worksheet. The Azz vector is changed so that there is not division by zero. The error on f(x) is that it must be an integer. I have attempted to use the vectorize to get around this. Is there another way to make this work?

Some time ago, I create a worksheet on DC lines.These are notes of studies done in the distant past.Someone correct me if I'm wrong.I thank you in advance.F. M.

Hello,I need some help with a solver block. I have attached the .mcdx fill. I'm trying to solve for 3 variable with 4 equations (constraints) which are a function of theta.I feel I'm going about this wrong.Any help is greatly appreciated,Ken

Dear all,I have a problem with the 3D iteration. Firstly, I construct an initial jxk matrix. Then, I try to iterate the matrix and to build up a nested matrix. I don't understand where the problem is and I am wondering if there is a better way to program this idea. I have attached the file. Thank you very much for your kind help!! 

hi for example if A=(a,b,c,d,e) and a=1, b=-3, c=4, d=2, e=-1,how can I choose "d"(minimum positive number biger than one)"A" is matrix

Hi there, I have a couple of calculation sheets and I am trying to incorporate them into a summary sheet. If I include sheet 1 first, it returns the valves from that included sheet. However if I include sheet 2 below it some of the values are failing saying that the variable is undefined, however it clearly is.  (Summary 1) If you look at Summary 2 however I have reversed the order of the included sheets and the opposite happens ?????Has anyone got an idea as to what the issue could be?? Its annoying because it says that there are errors in the worksheet but there isn't. I am actually trying to summarise 6 sheets, these are just two of them .Cheers

  Hello, Everyone. Is there a bug in the following: (1),(2), or (3) ?      Thanks in advance for your time and help.           Regards.

I am trying to use rnorm to create a vector of random numbers.The vector should have (density) units of lb/ft^3.  For some reason when I attempt to give the sigma and mu values units of lb/ft^3, the numbers come out incorrect and without the desired units.  Where should I look to fix this?Thanks,Jason

Dear Friends,Please help me to write an equation, which is attached.Thanks

A while back, I did a post on what software my students wanted to use in a graduate class on technical math.  They unanimously chose MATLAB over Mathcad because they perceived (correctly, I think) that MATLAB is pretty much the standard for technical computing.  I warned them that there was definitely a learning curve, but that MATLAB is extremely powerful.  At the time, they primarily valued the universality of MATLAB and weren't worried about ease of use.Fast forward to the last exam of the semester.  I wrote the exam solution using Mathcad and it was a very simple task, but they tried to work the exam in MATLAB (it was a take home exam).  I inadvertently wrote a couple problems that were easy to solve in Mathcad, but very hard to program in MATLAB.  By the end of the week, they were in my office asking if it was alright to use Mathcad.  Basically, the ease of use won them over.  Good news, indeed.I'm finding that the biggest practical barrier
